Idler arm slop A body Dart

The more I look into this I see what might be happening. Is the bolt supposed to be what the bushing swivels on or is the bushing supposed to be tightened down between the K frame and not move and swivel outside of the bushing? Looks like I should shim the bushing to take up the slack in the K member and make it lock down and not move when the bolt it tightened. Is this correct? If so, my problem may be solved.
